Example Embodiment

[0052] The embodiments of the present invention will be described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention. Detailed implementation modes and specific operation procedures are given, but the protection scope of the present invention is not limited to the following implementations. example.

[0053] The identification process of this embodiment is as follows figure 1 As shown, it specifically includes the following steps:

[0054] (1) Extraction of corneal emission spot center

[0055] When the infrared point light source illuminates the human eye, a bright spot will be formed on the surface of the cornea. Therefore, there is a white area in the image captured by the eye camera, which is the corneal reflection. When the infrared point light source and the user's head remain relative position unchanged, the corneal reflection is The position in the image remains unchanged, so in the image plane, the center of co...

Abstract

The invention discloses a head mounted eye tracker detection method, which comprises the steps of extracting the cornea emitting facula center; extracting the feature points of the pupil outline and fitting the pupil outline. The head mounted eye tracker detection method has the advantages that the position of the eye fixation point is worked out according to the anti-interference performance of an infrared light source, then, the positions of eyes during eye closing and eye twinkling are fit according to a tracking algorithm, the eye movement fixation orientation can be precisely measured, the precision of an identification algorithm is high, and the measurement on the eye movement fixation orientation at a high-precision requirement can be met.

Description

technical field [0001] The invention relates to a method for eye detection and tracking, in particular to a method for detection of a head-mounted eye tracker. Background technique [0002] Traditional eye detection and tracking methods mainly use the difference between the appearance and shape of the eyes and other parts of the human face. The characteristics of the eyes, such as black pupils, white sclera, round irises, eye corners, eye shapes, etc., can be used to distinguish human eyes from other objects, but due to eye closure, blinking, variability in eye size and position, different lighting conditions, orientation of faces, etc., these eye features will be reduced or even disappear. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a head-mounted eye tracker detection method, which utilizes the reflection phenomenon of the pupil to near-infrared light to locate the pupil. [0004] ...
